The Derevo are not a race unto themselves but a race of similar species. Similar to the different asian cultures. They are all different yet similar being similar cultures. The Derevo are like that.
The leaves talk and caress the mind of those who are willing to listen. We know what it is they say and it does not bode well for the civilized lands to our west. Woe to them I say, the land will return to it’s natural state one day.
-Enio Lacvite - Knowledge Seeker of the Rred Leaf
A small magical plant with a love for pulling pranks.
A vicious murder happens in a town that the party happens to pop in at. Under heavy suspicion as they are strangers, the party is forced to discover the perpetrator or have their reputations blackened, especially as more and more murders occur in the town, and mysteriously stop and restart when the party leaves to go kill off that evil necromancer who kidnapped the princess.
The only problem is that a demon, possessing one of the party, is the perpetrator. And the demon makes no signs that its living in the PC's head.
In fact, for all the party knows (except for the possessed person's), their companion is an evil murderer.
Do they try and execute their friend as he's a vicious murderer, and no evidence points to demonic posession? Or do they flee town with him, trusting him, and have their reputations destroyed?
